Just got myself a 2012 DS4 thp 200.
I knew the car was using some oil when I got it, but after giving it a proper engine cleaning I noticed oil again on the turbo.
Seemed like it was coming from around the oil pipe on top of the unit( partnmbr 037956).

Removed the little clip-on heat shield and tightened the bolt a bit.
This must have put some strain on the pipe because it started leaking more from the back where it is pressed in place.

Tried adjusting it by loosening the bolt again and re tighten, but now the pipe is totally loose and can be moved in and out.
So now the car can't be driven.

This is obviously a common part to fail, but how hard is it to replace it?
Have not found a well written guide anywhere.

Started yesterday and have gotten a good way on removing the leaking pipe. It's the lower connection that's hard to get to.
Just began wondering if the DS4 has a convenient service mode the bumper can be put in to get some well needed extra room?
